Notice of Staff Data Response and Issues Resolution
Workshop for the
Carrizo Energy Solar Farm Project (07-AFC-8)

The California Energy Commission staff will conduct a Data Response and Issue Resolution Workshop for the proposed Carrizo Energy Solar Farm Project (CESF). The purpose is to discuss the applicant's responses to staff's data requests, the Second Supplement to the Application for Certification (AFC), and to work toward resolving issues. All interested agencies and members of the public are invited to participate. The workshop will be held:

TUESDAY, August 5, 2008
Beginning at 6:00 PM

Carrisa Plains Heritage Association Community Center
10750 Carrisa Highway
(State Route 58, near Simmler and California Valley)
Approximately 44 miles east of Santa Margarita, CA
(Wheelchair Accessible)
(Map to Location)


The Energy Commission staff is currently analyzing Ausra CA II, LLC's (dba Carrizo Energy LLC's) AFC for the proposed development of the Carrizo Energy Solar Farm. Staff has provided the applicant three sets of data requests dated January 28, 2008, May 8, 2008, and July 25, 2008. In the workshop scheduled for August 5, 2008, it is expected the primary topics of discussion will be in the technical areas of Biological Resources, Noise, Traffic and Transportation, Soil and Water Resources and Visual Resources. Other areas may be discussed as necessary. Staff's data requests and the applicant's responses can be found on the Energy Commission's website: Following the workshop, staff will consider the comments it receives and will publish a Preliminary Staff Assessment (PSA) indicating staff's positions on the environmental issues affecting a decision on the applicant's proposal. The PSA will consider the completeness of the applicant's proposed mitigation measures, and the need for, and feasibility of, additional or alternative mitigation measures.


On October 25, 2007, Carrizo Energy, LLC submitted an AFC to the California Energy Commission to develop a nominal 177 megawatt (MW) net solar thermal power plant in eastern San Luis Obispo County, California. The 640-acre proposed project site is located immediately adjacent to California State Route 58 (SR-58/Carrisa Highway), approximately three miles west of Simmler. On December 19, 2007, the Energy Commission accepted the AFC as complete which initiated the Energy Commission staff's independent review of the proposed project. On July 3, 2008, the applicant filed a Supplement to the AFC describing changes to the proposed project. The primary changes consist of proposing that the solar reflectors be aligned in a north-south rather than an east-west direction, rotating and relocating the power block slightly east of the original location along the northern site boundary, reducing the length of the two air-cooled condensers, performing on-site manufacturing of solar collectors, and reducing the number of steam drums from twenty to eight in the solar field and from two to none in the power block. The Energy Commission is responsible for reviewing and deciding whether to approve applications for construction and operation of thermal power plants in California with a capacity of 50 MW or greater.
